Rectangle Type Meter - LK Series

LK-series is rectangle meter, 3 size for this type: LK-12, LK-10 &LK-8. Panel cut dimension is conformity with JIS C 1103.
LK-series has original design for instrument cover. It’s not only
suited for switchboard or panel instrument but also suited forelectrical or electronic set. LK-series is a reliable meter be fully
satisfied with standard JISC 1102-1~9 (IEC 60051-1 matching) andLK－8C

adopt a most suitable operating principle for measuring object.
Our products improve with realibility special specification foroverdue environmental conditions as cold resistance and tropicalspecification. Please consider to use our product on oversea such as
Frigid Zone and Tropical Zone.

LK－10CFEATURES► High quality and high performance meter.
► Flame Retardant Material Meter can manufacture by specify.
► Panel locked by 2 screws.
